An overall dynamic model for a high-rise building hot water heating (HWH) system was developed. This dynamic model was employed to analyze the characteristics of a HWH system and to simulate a pressure-temperature control (PTC) strategy. The dynamic responses of the water mass flow rate, pressure, temperature, and motor speed were studied. The simulation results show that the pressure control strategy is able to reduce the pressure fluctuations in the system and as well as interact positively with the thermal system in maintaining zone air temperatures at the chosen set points. The results also show that the use of pressure control strategy resulted in lower water mass flow rates in the system compared to the design mass flow rate. [ABSTRACT FROM AUTHOR]
